Answer:
Rhyming couplet
Step-by-step explanation:
A rhyming couplet is a pair of lines whose final words rhyme with one another, and that expresses a complete idea or message. William Shakespeare often used this poetic device at the end of his scenes, to sum up his work's main idea and to add a dramatic effect. Take a look at the following rhyming couplet found in Romeo and Juliet, one of Shakespeare's most famous plays:
"This precious book of love, this unbound lover,
To beautify him only lacks a cover."
